Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467210, here are decompositions:

7 + 31467203 = 31467210
11 + 31467199 = 31467210
29 + 31467181 = 31467210
41 + 31467169 = 31467210
43 + 31467167 = 31467210
53 + 31467157 = 31467210
83 + 31467127 = 31467210
107 + 31467103 = 31467210

Showing the first eight; more decompositions exist.
